This is a well-laid out and good looking supplement to Total Warfare (you need to have it in order to use these) that adds a number of new 'mechs to the game, each with all of the necessary record sheets. Best yet, having them in PDF makes it a snap to print out what you need for a particular game. The 'mechs themselves (as in the art) look pretty cool. At at total of 114 pages (including the covers), this PDF is a really good value for Battletech enthusiasts.
